Float Tanks have been growing in popularity over the last several years and many Float Center owners are using a variety of chemicals to sanitize their tanks.
Health Departments and Hydrogen Peroxide in Float Tanks.
The health departments around the world don’t quite know what to make of float tanks, some of them categorize them as pools, others as hot tubs and some they create custom regulations for. In the float industry the preferred method of sanitation is using high strength hydrogen peroxide weather it be food grade hydrogen peroxide or “technical” grade which has stabilizers in it.
Hydrogen Peroxide is preferred because unlike a pool or hot tub, the float pod is shut during use. A person is put inside the float tank and a door is closed. This is important because chlorine is a gas bound inside a liquid or solid and it “off” gases. This is an issue for floaters because the float tank can fill with chlorine gas and the customer will breath that in during the float.
Hydrogen peroxide on the other hand decomposes into hydrogen and oxygen, both of which are safe to breath. This is the reason peroxide is the first choice for float centers.
Unfortunately many health departments require the use of chlorine and bromine and do not allow Hydrogen Peroxide. The community is trying to get them to understand why it’s being used and how it is a better choice for health reasons.
How much 35% Hydrogen Peroxide do I put in my Float Tank?
Just like for swimming pools and hot tubs, you want to keep your hydrogen peroxide levels around 30 to 100 PPM (parts per million). Many float tanks are around 200 gallons and the float rooms are 300+ gallons. If you are starting with fresh water (with salt added) we recommend add a cup of 35 percent food grade peroxide to start, let it cycle for a few minutes and test the strength with peroxide test strips. Then slowly add more peroxide until you get a reading between 50 – 100 PPM.
How Much Hydrogen Peroxide Per Day After Residual is Built Up?
After a peroxide residual is built up, the maintenance dosage is between 1/2 and 3/4 cups per day. This will vary depending on the number floaters you have each day.
Should I use Food Grade Hydrogen Peroxide or Technical Grade in My Float Tanks?
Many people in the float industry gravitate using 35% Food Grade Hydrogen Peroxide because it does not have any added stabilizers. This is really a precaution because nobody really know what the effects of the stabilizers are on the skin, so for this reason the popular choice is Food Grade Peroxide.
34% Technical Grade Hydrogen Peroxide is the 2nd most popular choice. The technical grade is identical to the food grade except it has stabilizers added to the peroxide so it lasts a bit longer. If you’re trying to stretch a buck a bit further, this is also a good choice for use in float tanks. The amount of stabilizer introduced to the water is very minimal, in the order of 5 PPM (Parts Per Million).
At the end of the day, using 35 percent food grade hydrogen or technical grade hydrogen peroxide are both great choices.
